MAGTREX® 555 High Impedance Laminates

Rogers MAGTREX 555 high impedance laminates are the first commercially available low loss laminate with controlled permeability and permittivity. MAGTREX® 555 laminates enable antenna designers to expand the tradespace of their antenna design enabling design flexibility and optimization.

MAGTREX 555 materials are made from a unique combination of low-loss, high-resistivity ceramic filler and high-temperature thermoplastic matrix. This results in a flexible, through-hole via-capable system that is both mechanically and electrically stable. These laminates offer closely matched X/Y axis permeability and permittivity values of 6 and 6.5, respectively, and exhibit low magnetic and dielectric loss below 500 MHz. MAGTREX 555 high-impedance laminates also have a low coefficient of thermal expansion (CTE) in the X, Y, and Z axes, closely matching copper for enhanced thermal reliability. They are available in thicknesses ranging from 40 to 260 mils and come with or without copper cladding.
